Based on the principle of laser irradiation, combined with the optical characteristics of the transmitting system, the fully reflective co-aperture laser target design is integrated, and the advanced design of sharing one system for laser receiving and transmitting makes the whole laser target designation system more stable and reliable, with high energy concentration, compact structure and light weight to better meet the actual application requirements. Open frame OEM modules and various configurations of LRUs (line replaceable units) are available.
